Apparently to prevent this, but in reality to replace Alexander Obrenovich by Peter Karageorgevich, a military conspiracy was organized.
In 1903, after the murder of King Alexander Obrenovich, and the accession of Peter Karageorgevich, the constitution of 1889 was revived.
They started a military revolt, drove Michael also into exile (1842), and elected Alexander Karageorgevich, the younger son of Karageorge, as prince of Servia.
Not only Russia but Servia also was dissatisfied with such a policy, and when Alexander Karageorgevich, forced by public opinion, at last dared convoke a national assembly, that assembly's first resolution was that Prince Alexander should be dethroned and replaced by the old Prince Milosh Obrenovich I.
Prince Michael's great popularity in consequence of his diplomatic successes alarmed the friends of the exiled Karageorgevich dynasty, more especially when rumours began to circulate that the prince contemplated divorcing his childless wife Julia and remarrying.
But such laws and such acts only embittered political passions and greatly encouraged the adherents of Prince Peter Karageorgevich, who, having married the eldest daughter of Prince Nicholas of Montenegro and living at Cettigne, was supposed to enjoy the support of Russia.
The anti-dynastic party raised its head again, and in any Radical publications the expulsion of the reigning dynasty and its replacement by the Karageorgevich were advocated.
- The regicides proclaimed Prince Peter Karageorgevich king of Servia; and a provisional cabinet was formed, with Colonel Mashin, brother-in-law of the murdered Queen Draga and organizer of the conspiracy, as minister of public works.
Born in 1844, he was the son of Alexander Karageorgevich and grandson of Karageorge; in 1883 he had married Princess Zorka, daughter of Prince (afterwards king) Nicholas of Montenegro.
